Final answer:
The scopes used for cystoscopy, laparoscopy, and thoracoscopy are known as endoscopes, which are medical devices for internal examination and procedures.
Step-by-step explanation:
Scopes typically used for procedures like cystoscopy, laparoscopy, and thoracoscopy are all types of endoscopes. These devices are designed to explore the body either through natural orifices or minor incisions, allowing for both diagnostic and therapeutic procedures. An endoscope transmits light down one bundle of fibers to illuminate internal parts, while the reflected light is transmitted back through another bundle, allowing the operator to observe the internal view on a screen or through an eyepiece. Endoscopes can also facilitate surgeries by using attached cutting tools while observing the area, as well as obtaining tissue samples, such as lassoing an intestinal polyp for external examination.
